This invention relates to machines For operating vupon boots 'and shoesend, in vvthe illustrated embodiment herein disclosed, is shownesepplied to a machine 'torpreparing welted, unsoled shoes for thereception o'j the outsdle. Machines of this type ere known as welt'puttingl Vend decking finachines, an eiizunple being shown `in UnitedStates Letters `Patent No. 1,378,553, granted April 5, 1921', on myapplication. lit :is to be understood, however, that fthe severedfeatures et the present invention tre v,not llimited in theirirpplicetion to machines on ythis-type. y y

@ne of the objects of the invention 'is Lto provide a machine lot theabove indicated character with sini-ple nnd etective ineens -forreinovimgthe waste endslot the .welt that raire severed duringthe-butting or scarling operation end l'or preventing nu accuxnulntionolf warf. 'riud threiuflsupon the entters. i

A crin'dingly, one ol' the l'ezitures olfthe invention res les in theproi'ision el vetste end removing implements disposed :lirectly nboveund in sliding `engegement -ivith ithe respective welt-buttingIicritters .and .which nre :mounted luponfthe cutter czirriers and nrelaterally actuated across the cutters to discharge the waste end-s andto scrnpeotlthe wax lend threads therefrom sitter erich but- `tingl orscaring opeintion.y "Moreover, Athe ineclninisin's tor effecting theactuation ort the waste-renioving implements nre ln'ioui'ited upon andere movable with the cutter cnriiiers andere also disposed on the outersides thereof where space is unrestricted.

Another objeet'ot the invention .is to provide n. mnchineoft thisgeneral lclass `with vineens for' lasting in the uppers under determinedpressure prior vto ther te,

operation and to etlect this result .:iuteinn-tically so es to relievethefoperrt'tor oli. the cure and elfort heretofore required for thispurpose.

Therefore, Linother Atieeture of the linvention contemplates theyprovision A'ot' ipowerope ated I.means tor eutoinnticelly forcing thewelt supports or crense 'finders 'inwafif'dly under predeterminedpressure which pressure may be applied subsequent to `ithe welt-`butting operaltion, `whereby the uppers are lasted 1n independently ofthe operzitornpis't Aprior to the tsckmg operation. As shown herein thepower-operated means acts through e spring, by compression ot' wl1ichthe required pressure is applied to the velt supports. I

Another Object of the invention is to provide adequate ineens forcausing` :the welt'- butting cutters to .bevel oft the ends` ot thewelt, not only longitndinell-y'thereof butfalso transversely outwardwith. respect thereto, in suchinitnner'that thestitches remain 1n` tactthroughout substantially theifull'length ot' the scerts, while .the endsoft the welt are cutoti squarely.

To Vthis end, a `:feature tot `the invention lies `in the provision of`welt `supports orerense finders that may be ndjustedfto enyfdesiredlongitudinal nnguhirity to the plane of-..the

cutters `whereby Vthe vrequisite..longitudinztl bevels areproduced, :indmoreover, that are so trnnsversehv inclined V:1nd f'concnved .to receiveand support the inner portions ot the welt adjacent .the-stitches .insuchpositiou that the welt-butting cutters ibevel eti' the welt ends tothin edges tinnsverscly outward without cutting the stitches et theinner edges of the welt. lluirtherinore, sheerv cordiince with theinvention, rn'tnin ipertions of the frame being broken aivay to disclosecertain parts of the operating mechanism; Fig. 2 is a sectionalplan viewon the line 2-2 of Fig. l, showing the Aswinging side frames, theoperating mechanism for the Welt-butting' critters, and the mechanismfor removing the severed Waste ends of the Welt; Fig'. 3 is a sectionalYplan view show-V ing' one of the Waste end removing` mechanisms in anintermediate position during its operation; Fig.V e is a vieii7 in sideeleva-- tion of the right-hand side frame with its Welt-butting andtasking mechanism, certain parts being' broken away from the inside faceof the side frame for the sake of clearness; Fig. 5 is a detailed viewin vertical section of theloii'er end of one ofthe taclrer mechanisms;Figs. 6, Tand 8 are vdetailed views in side'elevation, illustratingdi'lierent positions ofa welt-batting' cutter and tacler'Y mechanism atdifferent times 'during' the Welt-hutting andv taclring operations,these views being similar to that of Fig'. 4; Figs. 9 and l0 are views,partially in section and partially in side elevation, of a portion ofthe mechanism for effecting the automatic iasting in` of the uppersubsequent to vthe Welt-butting' operation, said viewsrespectivelyillustrating the mechanism at different stages of itsoperation; Fig. ll is a view in side elevation, showing the relativepositions of the crease linder, heel-seat guard, presser foot,.andWelt-batting' cutter in the process of scarling oil' the end of a Welt;

and Fig'. 2O is perspective View of one of p the Welt-batting cutters.

ln the preferred embodiment of the invention illustrated 1n the drawnand j? y with particular reference to Fig'. 1,-the inachine is providedin general with mechaiiism for supporting' the shoe inoperative position"and the rear ends of the Welt in position for the biitting' operation.lmechanism forbutting bothzof the Welt .eiidssimul- .butting and taclcingmechanisms, While a bracket 88 is bolted to a table 40 cast on the upperside of the goose neck 26 and carries a tack separating and deliveringmechanism 42. VAny suitable tack separating' mechanism may be employed,although the prefered form is that shown and described in the patenthereinbefoi'e referred. to.

The moving' parts are driven by the rotation of a driving shaft 44:which is disposed at the rear of the machine and extends transversely ofthe head thereof, and which is enveloped by means of a guard plate 4:6.The driving shaft 44 is normally at rest but may be connected at thewill of the operator by means of a single revolution clutch of anyWell-known form (not shown) to a power shaft i8 which is continuouslydriven by a belt cooperating' with a pulley 50.

As is usual in machines of this character, the shoe is supported andpositioned vertically for the Welt-biitting and tacking operations bymeans ofthin plates usually termed Welt supports or crease iinders (Fi2, 4, l1 and 1S), that are carried at the for- Ward ends of each of theswinging Vside frames 32 and 34 and which are inserted in the Weltcrease at each side of the shoe substantiallyV at theV rear end of theinseam. It will be understood that, as is common practice in this typelof machine, the crease finders are forced intothe Welt crease by theinward movement of the swinging side frames 32 and 34; Vabouttheir pivotrods 28 and 30, the crease `finders performing the function ofsupporting' the shoe during the Welt-butting and tacliiug operations. Inaddition to their usual function and by reason of further inuf'ardmovements imparted thereto independent of the operative after theWelt-butting operation, they also serve to automatically last in theupper just prior lThe back gage may be suitably adjusted in position bymeans of a locking handle 5G. The back gage 54 and its adjustablelocking handle 56 form no part of the present iufit) 'ventiom .except asthey perform .necessery vof which are attached to the grear -ends of therespective side frames. order that the side fremesgmay move atogether,lthy are provided with intermeshing toothedsY ments 60 und G2,respectively..throughwhich the lower ends o-f the pivot rods'QS and 30extend. A trezidle mechanism is provided torovercome the force-of the'spring ')Send bring together theorem-se finder-s carried by the forwardends ofthe Vside frnmesfinto position .to supporteshe-e and theendsofVthe welt for theogeretionsto be performed thereon.

Referring particularly to Fig. :9,ithis biellcren-k lever`is provided with :it -verticel erm .74 having socket which receives one.end of a .coiled spring; 76, the other end of' which Vis seated in nsocket fo-rmedlinen erm t78 which .projects upwardly and has two .legswhich reer ends 8d of the respective:swinningrside frentes'SiI end 554i.

The treedle di is normally held in raised position by :t spring Sticonnectingil .it toithe column 2li whereby the coiled sprin is normallyuncompressed, :is-sliown in Eig. 9. Vifhen the treedle 64C is depressed,howeve". the loweringof the treadle rod (S8 operates through the bellcrenlrlerer .TO-7d andthe spring' .7G to move the vertical-erm 785to theleft which operates upon the inner ends of thetwo struts 82 so as tobring the struts int@ position approaching; alinement. Consequently thereer ends of the side 'fr-times 32 and 34 are `forced,spartiniopposition to the fiction of the spring` 58. This outward movementofthe rear ends of the side frenes causes a` corresponding inwardmovomentlof .their front ends endY therefore lbrings the creeseiinders52 into the welt crease of the shoeiihich previously .been placed withits heel end `ugeinst the back gege 5i and which is held `by theoperative at :1i-'proper height.

(Win- 'tinueddepressionof the ireadlc will, 1however, continue .to rrotiite the rockshafii ft2, which movement is utilized through suitable `mechanism(notshowir) to operate the single. revolution clutch, hereinbefo-reyre-. -ferred i-to, in `order to effect an operative drivingconnectionlbetween the @power shaft 48 andthe driving shaft 4.4, whereby themechanisms for Operating' Athe vveriousvmoving pnrtsof'the machine aresetinto motion. No description of the meens for per'fformingx lthis'function is deemed necessary inasmuch .es it pertains onlyv indirectlyrto the present 1 invention. A full. description of the pri ferred formoffinenns for accomplishinev this resultmuy be found intheabovementioned patent -to `which referencemay be Ihzid if desired.

l Gil In order to render it unnecessary for the operative to hold'hisfoot on the treadle 64 afterv the driving shaft 44 and the variousoperating mechanisms actuatet. thereby have been set into motion andduring the continuance of their operations, automatic means is providedfor locking the swinging side frames 32 and 34 in the positie-ns towhich they have been moved by the depression of the treadle. Thislocking means is illustrated particularly in Fig. 1 and coinprises avertical arm 98 that is secured to the left-hand end of the roch shaft72 and which is pivotally connected at its upper end to the forward endof a rectangular rod 100.A The rear end of the rod 100 extends through arectangular opening in au arm 102 depending from and pivote'd freely ona horizontal stud`104 carried by the machine frame. The lower end of thearm 102 is normally pulled forward by a 'spring 106 connected betweenthe arm and the frame. lNhen the machine isin a position of resta pin108 projecting outwardly from the periphery of a disk 110 that issecured to the left-hand end of the driving shaft 44 is in engagementwith ,an upwardly projectA the arm 102 to an angular posit-ion with re'lation to the rod 100, whereby the corners of the opening in the armabove and below therod are caused to bite and bind on the rod and act asa lock to prevent the rock sha'tt'72 'irolnb'eing' rotated to initialposition bythe extended treadle spring S6. Y

The swinging side trames remain locked in l their inner slioefsupportingpositions during the cycle oi operation ot the several mechanisms whichoperate upon Ythe shoe and until just subsequentr to the time when thesingle revolution clutch 1s thrown out to disconnect the driving Shaft44 from the power shaft 48, at which time the pin `10S on the peripheryof the disk 110 is again.v

brought into cooperative engagement with the extension 112V ot thepivotally Ymounted locking arm 102. This locking arm is thereby returnedto its initial position normal to the rod 100 so as to release said rodand theiroclt shaft-72, whereupon the .spring 58 which connects therearends of the side frames 32 and 34, operates to swing the framesoutwardly about their pivot rods 28 and 30 and thus release the shoefrom its Vengagement with the supporting crease finders 52. VThe treadlespring SG also `functions to Vrestore the treadle G4 and Referringparticularly to Figures 1, 2

' and the welt-butting mechanism will now be described. The actuation ofthis mechanism is effected through a connecting rod 116, one end ofwhich is associated with a crank `118 forming a part of the drivingVsha't 44 and the otherend of which is connected toa piston 120 which isguided within a cylindrical way 122 cast centrally in the lower partofthe goose neck 2G, Projecting from the forward end of the piston 120is a connecting rod`124, which is providedrwith an H-shaped head 126(Fig. 2) which lies horizontally with the legs of the H" pointingoutwardly toward the side frames 32 and 34. The slots 128 and 130 formedbetween the legs of the H carry slide blocks HB2-and. 184 which aredrilled yvertically Vfor the reception of vertical pins 136 that arecarried in ears 138 that project inwardly from the welt-butting cutteroperating slides 140 and 142. With this construction, a rotation of thecrank 1,18 to withdraw the piston 120 within its guideway 122 causes theslides 140 and 142 to be actuated inV a rearward direction to e'cct t-heoperation ot the welt-butting and tacking mechanisms. The slides 140 and142 are mounted 'tor sliding moven'ient in the Vrespective sideliran'les 32 and 34, which, in their supporting positions, are usuallyat an angle tothe line loi" movementot the piston 120. Irrespective ofthis aiigularity. ille slide block connections just described betweent-he slides and the H-shaped head 120 of the connecting rod 124, insureproper operation, inasmuch as the slots 12S and 130 in the H-shaped headprovide iter outward movements Vof the sliding blocks v132 and 34 as theslides are actuated.

Since the mechanism carried by each ojt the side frames is likel theother except that it is reversely disposed, it will be sufficient todescribe the mechanism at one side only, and the mechanism upon the rio'ht-hand side frame y34j will be used to disclose the construction nowtoV be described. Referring particularly to Figs. 2 and 4, whichillustrate the various mechanisms on the side frame 34 in positions ofrest, the welt-but tingcutter slide 142.1ests upon a way 146 For thepurpose of producing a bevel or scarf having the characteristicshereinbefore enumerated, the crease finder 52 is provided with apeculiarly shaped and inclined upper surfacev 200. This surface isinclined transversely downwardly from its upper' outer edge toward itsinner edge which is curvilinear in form with the maximum curvature atthe end of the crease finder adjacent the guard plate 198, as shown inFig! sai-d welt is so positioned thatthe` Ywelt-- butting cutter 154,though ittravels in a horizontal Vplanescarfs olf theend of the weltupon a bevel which, with respect to the normal plane of `the w-elt,isinclined both longitudinally and transversely outward in such manner asto leave the inseam stitches intact andY also to cut olif the end of thewelt squarely, as illustrated particularly `in Figures 11 and 15. Thiswill be clear from Figs. 13 and 14 which are transverse sectionsof theright hand welt support and crease inder on thelines 13g-13 and 14-14 ofFigure 12 respectively. VIt will be noted that the outer edge of thewelt ils held higher than the inner edge, the upper surface of thesupport vbeingtransversely inclined downwardly and inwardly with respectto the shoe. In Figure 14 they dotted line represents the plane of thecutting edge of the knife when it is about` to begin its cut. The cutbegins on the outer margin of the welt (Figure 15) and graduallyrogresses inwardly until it extends entire y across the portion of thewelt which lies outsidel the stitches (Figure 18). The

knife hassnow reached a point above maximum longitudinal curvature ofthe welt support which is greatest onthe inner edge otthc welt supportand shades out to little or nothing at the outer edge. The welt isforced into this concavity of the welt support by the presser 162,andthe knife, in finishing its cut, co-operates with the odge 206, whichis parallel to the knife edge, to formV a. square end on theV welt asshown in Figure 15. Obviously the length of the longitudinal bevelproduced by the welt-cutting cutter is determined by the longitudinalangular-ity or inclination of the upper'surtace of the crease finder 52with respect to the path ot travel of the cutter, and this inclinationmay be altered to obtainany length of bevel 'of a spring pressed pin246.

sired by loosening the Set screw` 208 (Fig. 18) and shifting the creasefinder angularly in its guideway 176, it being understood that the sidesof this guidewa-y are formed on arcs of circles having the joint betweenthe crease finder and the guard plate 198 as the centre-` f Since themovement of the welt-batting cutterslides 140 and 142 also actuatesthctacker mechanisms, a description of the op` eration or" the welt-huttingmechanism will be deferred untilthe tar-ker mechanisms have beendescribed. s For an understanding ol the tackerVv mechanisms, referencemay be had particularly to Figs. 4 and 5 which illustrate the tackermechanism associated with the right-hand swinging side frame 34, whichmechanism is identical with that carried by the left-hand side trame32.' The tacker mechanism comprises a driver bar slide 212 which isseated for vert-ical sliding movement in a vertical rectangular grooveor way in the forward edge of the side frame, which way is closed by afaceplate 214. This slide 212 is bored longitudinally 'for the greaterpart of its length for the reception of a cylindrical dri-ver bar 216.At its lower end the slide 212 is provided with a reduced bore throughwhich a tack driver 218 extends (Fig. The tack driver is secured to thelower end of the driver bar 216 by a nipple 220 in the usual manner.Also the lower end ot' the ydriver bar slide 212 has secured thereto bya nipple 222 a suitable tack nozzle 224. At its upper end the driver baris provided with a head 226, the rear end ot which is slotted andreceives a vertically disposed track 228. A roll 230 is carried by thehead 226 which engages the track 228 and guides the bar in its movementthrough the driver slide. Thejextreme upperend of the driver bar carriesa conical cap 232 which is engaged ,by a socket on one end of a coileddriving spring 234. The other end of thc driving spring is connected toablock 236 having a pin secured ina bearing 238 at the rear side of thedriver bar slide 212.

Pivoted by its lower end at 24() in a vcrtical slot iormed for itsreception at the up per end of the face. plate 214 is a latch lever 242carrying at its upper end a roll 244 whichis normally held in the patho1 movement of the driverbar head 226 by means The .inward moven'ient ofthe lever 242 is limited by an ear on the lever engaging a stop pin 248mounted inthe 'l'ace plate 214. The driver head 226 is provided with abeveled surface 250 soI located that on the upward movement of thedriver bar216 the roll 244-is forced to one sido until the head hasreached a position above the roll when said roll snaps back beneath thchead and supports the driver har against downward movement.

Theplete/290 is` provided with un elongioted slot. 25%, through whichprojects zi bolty 29o.' for rigidly securing seid plete und thereforethe tube section 28S in any ndjusled. position. The upper end otthe-tube section 238 isv enlurged :ind hais` n telescopic connection Q98with the lower end of the delivery tubeQSt, while the lower end thereofis tapered and adopted to lit within `tunnel shaped open ing" len-clin@`to the inclined mennen/282. The inclination ot the tube section 288lelwzvvs corresponds to toutl ot the taelw'ey 282. By ineens ot' thisConstruction it is obvious that regardless ot the height of thetool noz-Zle 22e in its raised loading position,y the spring 234, since thedriver bar 216 is-held from down ard movement by reason of its headbeing above Vthe roll 244 on the latch lever 242. Just as the tacknozzle reaches the shoe, as shown in Fig. '7, the cam 254 on the driverbar slide engages the boss 252 on the latch lever 242 and pushes saidlever to the right, as viewed in Fig.4, so as to withdraw the roll 244from beneath the head 226 of the driver bar 216. This immediatelyreleases the driver bar to the action of the now fully tensioned drivingspring 234 and the tack contained in the tack noz, Zle 224 is driveninto the shoe by the tack driver 218, the parts at this time being asshown in Fig-7.

The driving crank 118 has now passed through a half revolution and thereturn forward movement of the welt-betting cutter slide 142 isthereafter effected, first relatively to the carrier152 which causes thelinks 148 and 150 to tilt backwardly until the rear end of the carrierengages the shoulder 154, as shown in Fig. 8. This backward tiltingmovement of the carrier raises the forward end thereof and thereforeelevates the welt-butting cutter 154 from the Shoe.

The continued forward motion of the car-V rier slide 142 returns .thecarrier and the cutter to theirinitial positions, as shownv in Fig. 4,and during this movement the carrier actuates the link 262 to reverselyrotate the segment 258 and raise the driver bar slide 212 from itslowered position, indicated in Fig. 8, to its initial raised position,as shown in Fig. 4. Since the head 226 of the driver bar 216 rests atthis time upon the upper end of the driver bar slide, the driver bar andone end Vof the driving spring 234 are both raised together until thelatch leverV 242 is tilted outwardlyV by the engagement of the cam 250with the roll 244, and the head 226 eventually rests upon said roll andis held in .its raised position with the driving spring uutensioncd.

During the rearward movement of the cutter slide 142, the friction plug270 offers sufiicient resistance to prevent movement of the segment 258and associated tacker-mechanism during the first part of the operationof the crank 118 to lower the cutter 154, and provides means forensuring that the cutter carrier 152 is moved toward and from the.

welt support or crease finder about its pivotal connection with thecutter slide 142. The plug 270 performs a like function to restrain thecarrier from n'ioving relative to the slide at the start of the returnforward movement, thus raising the cutter from the shoe before thecarrier is advanced by the slide to its initial forward position, whereit is in readiness for another cycle of oper ations.

From the foregoing description it is clear that both the niek-battingand tacker mechanisms are operated by a single actuator' and in sequenceto first butt the respective ends of the welt and thereafter drive thetacks.

As has alreadyfbeen stated, the pressure of the creasel finders 52against the shoe during the welt-batting operation is relatively light,being only such as is necessary to support the shoe. in position whilethe ends of thewelts are butted. According to the Y present invention,power-actuated means is provided for automatically increasing the inwardpressure of the crease finders .subsequent to the welt-butting operationfor the purpose of lasting in the upper and associated parts andbringing' them intoV their final positions preparatory to the tackdriving operation.

Referring particularly to Figs. 1, 9 and 10, this end is accomplished bymeans `of a member BOO which is secured to the forward end of a rod 302that is carried beneath the H-shaped connecting rod 124. This rod 302 isslidably mounted thereon in an `apertured depending lug 304 and adownwardly projecting cylindrical bearing member 30G;

' The inner end of the rod 302 is screw-threaded into a sleeve 308 thatis slidably positioned in a cylindrical opening in the bearing member306, Vand disposed betweeny the lug S04-and the forward end of the ve308 is a coiled spring 310, the strength of which may beadjusted asdesired by screwing the rod 302 into the sleeve 308.

Subsequent to the welt-batting operation and while the cutteristraveling over the guard plate 198, the, rearward move- Vment yof thepiston 120 brings the member 300 into coopera-tive engagement with thehead of the arm 78 in the-sockets of which are located the inner ends ofthe kstrut-s 82, constituting the operating toggle of the shoe to anincreased predetermined pressure and eifecttlie lasting in thereof intoiinal position. -The lasting operation is so timed that the .upper isproperly positioned to be secured to the insole prior to the operationof the tacking mechanism. This automa-tic lasting operation `is of.special importance since uniform results are secured, by `reason ofbeing accomplished cutters 154 are apt to `become gummed up with waxedthreads and excess wax, while the severed waste ends .of the weltfrequently become jammed in between the cutters and the presser feet 162in such manner that considerable difficulty Ais experienced `indislodging them. Provision is, therefore, made for @scraping off the`cutters' and removing the waste ends :subsequent `to .each

welt-butting operation.

This means is best shown in Figs. 2, :3, 4,'

16 and 17, and having reference to these iigures, the scraping andwaste-removing mechanism associated vwith the left-.hand side frame willnow be described. This mechanism comprises a substantially trianguiarscraper, or removing implement :312, which is located directly `abovethe cutter 154 in sliding engagement with the upper surface thereof. Theimplement 7312 is fixed to the inner end of a -rod 314 that is laterallyslidablethrough an aperture inthe forward end of-the cutter carrier 152`and projects voutwardly therefrom. The outer end ofthe rod 314isprovided with a slide ,block 316 which is fiXedly keyed thereto andwhich is adapted to slide within a way .318 provided in a lbracket 3 2()that is k.bolted `to the outside of the cutter carrier. This bracket 320is provided with ya laterally and forwardly extending flange. orprojection 322, the outer end of which constitutes a bearing 4for anoperating lever 324, having a pair Aof spaced `arms `326 which straddlethe bearing member 322 and which are piv- `otally mounted thereon 'bymeans of a pivot pin 328. The operating lever 324 is provided vwith arearwardly projecting arm .330 having a boss 4L332, wh-ich extends into,and cooperates with, -the sides of a groove or recess 334 that isprovided in the upper face of the slide block 316. The operating lever324 also yembodies -a head 336 in a recess of which va spring-pressedpin or detent 338 is disposed. The end of this pin lis adapted ytoproject into a suitable recess in the bearing member 322 to locate thepivotallv mounted operating lever 324 in proper position during aportion of the cycle of operations, as will be hereinafter more fullyset forth. The operating lever 32.4 is furthermore provided with anextension or :tail piece 340 that vis adapted for cooperative engagementwith one vend of a yielding stop or bumper 342, that ris pivotallymounted upon a v.vertical pin 344 that projects ldownwardly from theupper wall 346 of a laterally eX- tending box-like casing343,constituting an integral part of the face plate 276 that Ais bolted tothe outside of the side frame .32. The other end of the bumper 342 isprovided with a socket which receives a coiled spring `349 `ivhichserves the purpose of absorbingthe shock occasioned by the engagement ofthe tail piece 340 with the opposite end of the bumper 342, as willhereinafter appear.

lith the exception `of the spring-.cushioned bumper 342, the other partsof ;the re.- moving and scraping mechanism already described are mountedupon, and 4are movable with, the .cutter carrier 152 and thereforeparticipate in the back and forth and up and down movements of saidcarrier and its welt-butting cutter.

After the lwelt-b utti-ng cutter has :been dropped from its initialraised position (Fig. 4) to its lowered A operative position, 4as shownin Fig. 6, ,and vduring the rearward cutting stroke thereof, thescraping and `removing mechanism remains idle in the position shown inFig. 2, 1except for a bodily movement of translation. Duringthismovement the mechanism is maintained in position by thespring-pressed detent 338. Subsequent .to the welt-b utting andtackingop occupies the position indicated in dot-and.-

dash lines in Fig. 2, and having been raised in position, 1s broughtinto cooperatrve ,relation with a cam member 352 that -is bolted to theunderside of the upper wall 346 of the l outwardly projecting c asing`348.

During the return movement of the cutter, the roll 350 ytraverses thecam 352 and 4is progressively forced inwardly to a posit-ion illustratedin Fig. 3. The operating lever 324 is thus rotated about --its lpivotand, through the agency of the slide block 316 and the rod 314, thescraping and removing implement 312 is actuated in `a lateral inwarddirection. Thus, the scraper is caused to slide over the upper surface.of the cutter 154 whereby any waxed threads and wai: are scrapedtherefrom and the severed -waste en dsof the weltare removed frombetween the cutter and presser foot. A spring 354, which surrounds thevrod 314, serves to cushion the inward movement of the scraper.

As the forward return morement .of the cutter carrier and cuttercontinues, the tailpiece 340 is brought into engagement with theVspring-cushioned bumper 342, which serves to actuate the operatinglever 324, the slide block 316, the rod 314 and the implement 312 in theopposite direction into their initial positions as shown in Fig. 2,where they are restrained by the springpressed detent 338. Asalreadystated, the shock of this engagement is taken up by the spring 349. Theposition of the bumper 342 is determined by an adjustable setscrew 356in the forward end of the casing 348.

The cutter carrier and cutter having been returned to their forwardraised positions,

as shown in F ig. 4, the scraping and removing mechanism just describedis also elee vated in position, the roll 350 being in the plane of thecam 352, in which position the cycle of operations of the machine isarrested.

From the foregoing description it will be understood that the respectivecutters 154 are scraped and cleaned simultaneously and that the severedends of the welt are removed and ejected inwardly by means of thescraping and waste-removing implements 312. Moreover, the actuatingmechanisms for the waste-removing implements are located on the outersides of the cutter carriers where ample room is available for theirmounting and whereby the restricted space between the respectiveswinging side fra-mes is left as free as possible from obstructions.

Although the invention has been set forth as embodying more or lessspecific structural details and arrangement and location of parts, thoseskilled in the art will understand that many modifications may be madetherein without departing from the spirit and scope of the invention.
